Notice:
Be sure to follow the diagrams below when making your own cables.
Do not connect the cables shield conductor to the ground lug or
allow the shield conductor to come in contact with the XLRs
outer casing. Grounding the shield could cause a short circuit
and erratic behaviour.
Line termination:
When longer runs of cable are used,
you may need to use a terminator on
the last unit to avoid erratic behaviour.
Using a cable terminator will decrease
the possibilities of erratic behaviour.

5-pin XLR DMX connectors:
Some manufactures use 5-pin XLR connectors for data transmission in place of 3-pin. 5-pin XLR fixtures
may be implemented in a 3-pin XLR DMX line. When inserting standard 5-pin XLR connectors in to a
3-pin line a cable adaptor must be used. The diagram below details the correct cable conversion.

DMX setup
Termination reduces signal
transmission problems and
interference. It is always
advisable to connect a DMX
terminal, (resistance 120
Ohm 1/4W) between pin 2
(DMX-) and pin 3 (DMX+) of
the last fixture.
